Application filed. April 7,

'lhis invention relates particularly tosuch forms 01" railway cars as are used for hauling coin or ore from mines and for similar purposes. The particular type hereinvolved contains a frame comprising side sills and end structures joining the ends of the side sills, the frame being supported on two axles which extend crosswise of the side sills and each axle b ing supported by two wheels, one wheel being at each end of the axle.

Thus the car is supported by tour wheels, two wheels each side of the car resting on one of the track rails.

The object of the invention is .to provide automatic adjustability of the axles when the car istraversiug an uneven track, in order that all of the wheels may remain down in engagement with the nits. in the absence of provision in such a car adpt tion of the height of the wheels to depressions and elevations in the track rails, there is danger that one wheel may be raised above and clear of the adjacent rail a thus allow sidewiseniovement of that and its axle and the other wheel on axle, whereby that pair of wheels be come derailed, whereby the car becomes upset or wrecked. Usually such mine cars-are more;L in trains or trips,1and'it' one car becomes derailed, thatserves as an obstruction and causes the wrecking of other cars, whereby operation of trains on that track must be suspended. Such suspension is usu ally a serious loss.

further object 01 the invention is to provide for excluding dirt from the axle bearing. a

In my invention provision is made for permitting downward movement of the end of the axle it the wheel on said end or" said axle is passing over a part of the rail which is so low that the adjacent wheel would be held free from the rail, it the axle were held at a fixed elevation relative to the frame of the car.

Fig. 7 is plan showing the wheels and frame of the car, portionsfbeing broken away.

Referring first to Figs. 1, 2, 3 and 7 of the drawings, A, Aare the side sills ota mine car. in the form shown by thedrawings these sills are steel channels having flanges, Bi directed outward. To each side sill is attacheda box, A havinga base, If. shaped to fit against the inner faces of the flanges and against the adjacent upright face of the web otthe channel. Bolts or rivets, A extend through the ends of the base, A", and through the upright web of the side sill for immovably,securingthe box and its baseto the side sill. V v

The base, A has an aperture .approx1- i'nately on the axial line of the box and larger than the diameter of the axle, B. This enlargement-may be effected by making said aperture elliptical, the longer axis of the ellipse being upright, or. the enlargement may be effected by making. the-aperture circular or other suitable shape. Atube, B extends around the axle and through-the web of the side'sill and a short distance into the base, A the web andthe base bein g suitably recessed for this purpose. By thus seating each end of the tube, the entire; tube is given a fixed position relative to the side sills, and at the same time the tube serves to add stability to the sidesills. i

The hub, '0 ofa track wheel, C,.surrounds the axle. The outer end otsaid hub is closed and bears against the end of the axle. Between the huband the axle are anti-friction rollers, G On their outer ends the rollers have short journals, G which extend into an annular groove, C formed in the end of the hub. Each roller has at its inner end a similar journah-(F. A collar, C is applied to the inner faceof the hub at the inner end of the hub and secured to-the hub by means of rivets, C. The collar has a flange, -C extending be;

tween the adjacent journals, C and the axle, B. By means of this flange and the engagement of the journals, C in the annular groove at the outer end of the hub, the rollers are held in position in the hub when the wheel is not on the axle. On the part of the hub which is within the box, A there is a circumferential channel,

C At each side of the hub an upright key, C extends through the box and is positioned tangentially to the hub in the channel (in Fig. 7, these keys are placed horizontally). These keys hold the hub to the box and, as already described, the box is immovably s., lied to the side sill; and, as already described, the end wall of the hub extends across and-bears against the end of the axle whereby the axle is held against endwise movement.

The interior diameter of the axle tube, B and the diameter of the aperture in the base of the box are made enough larger than the diameter of the axle, B, to allow up and down movement of the axle in the tube. Normally the upper part of the tube rests on the upper face of the axle. 31a when the track is irregular so that the portion of the rail above the adjacent wheel is low relative to the parts of the track on which the other three wheels rest, this wheel may descend to the extent of the distance between the lower face of the axle and the interior of the lower part of the tube when the axle is in its elevated position or to the extent of the play allowed in the tube b cause the interior of the tube is of larger diameter than the diameter of the axle.

, In Fig. 1 a bottom plate, D, is applied to the lower flanges of the side sills, said plate being wide enough to extend from one side sill to the other and overlap the lower flanges. Rivets, D extend through said plate and said flanges to secure the plate to the side sills.

. Under this arrangement, the load of coal or other mineral will extend into the space between the side sills and rest on the bottom, D. Then the tube, 13 constitutes a fixed wall to keep the coal from hearing on the axle and interfering with the movements and lubrication of the axle. In Fig. 4: the bottom, D, is shown resting on the upper flange, A of the side sill, A. That construction does not allow filling the space between the side sills with coal.

Referring now to the changed form of Fig. l, the base, A has a flange or neck, A extending into the tube, 13, to the plane of the flat face of the side sill, and the axle has a circumferential flan e or collar, B which is adapted to rest inst said tlai Le, A of the base, A In this construction,

the interior of the tube is larger than is shown in Fig. 1, if the axle is to be the same size as 1n Fig. 1. Thus the axle bears only against the part of the box, A through which the axle extends.

In Figs. 5 and 5, the construction is the same as in Fig. i, excepting that the up aer part of the axle flange, B and the part of the base, including the flange, A above the axle are cut away to the height of the inner face of the tube. This allows the axle to bear against the upper inner face of the tube, and yet the flange or rib, B is pres ent on the axle to engage the end face of the base flange, A, to prevent movement of the axle outward toward the wheel hub.

In Fig. 6, the structure is the same as in Fig. 41-, excepting that the base flange or.

neck, A is extended far enough through the side sill to form an extended bearing for the axle and to make it unnecessary to extend the tube, B into the side sill. A cap srew, l3, secures the tube to the neck, A The axle flange or collar, B is again present to bear against the end face of the base flange, A". In this structure, the axle tube, B need not be as strong as in the form illustrated by Fig. 1, if the axle does not bear directly on that tube, and the base, A and the elongated base flange, A afford ample stability and support for the axle.

In all the forms, even in the form shown by Figs. 4 and 5, in which the bottom, D, is above the axle, the tube, B seals the axle bearing against admission of dirt or grit to the axle bearing.

In the several forms, the tube, B is to be regarded as supported by the side sills, even though the tube makes engagement with the axle box as well as with the side sill; or, even if the engagement or contact made by the tube is entirely with the axle box. In some of the forms, the larger con tact is made with the axle box. See, for example, Figs. 4 and 5. In Fig. 6, the tube does not make contact with the side sill. But the axle box is supported by the side sill. Hence the tube is supported by the side sill whether there is or is not direct contact between the tube and the side sill. In Figs. d and 6, the axle does not make contact with the tube.
